Rubber hasn’t always been man-made, it used to come from the Rubber Tree plant. Native to the Brazilian rainforest, this plant was of huge economic value. Rubber was made from the white latex secretions from the phloem (characteristic of the Euphorbiaceae family). Henry Ford lost millions in the early 1900s when he tried opening a Rubber Tree plantation. The project failed after farmers and biologists realized that the trees naturally grow in the understory of larger Amazonian trees that create a specific microclimate. Lesson learned, don’t mess with Mother Nature.
